woocommerce variable products problem

For the past year, I have had a PHP process running that inserts products into a WP database.
They are variable products.
Everything has been working perfectly but in the recent WooCommerce update, 2.4.x, the way product data is stored changed a bit for variable products and my process is broken.
The products are still added but not completely correctly and I have to go in and edit them in wp
    *admin before they show on the site. (caringsunshine.com).
I assume that editing the products is changing the data to the new format.
Please do not bid on this project unless you are a true expert with WooCommerce and keep up on the changes that are being made in new releases.
The code we use is very clean and the changes will probably be simple if the right person is involved.
On the other hand, this is not a project for someone to learn WooCommerce.
